Stepien et al reported the Lichen Planus Activity and Damage Index (LiPADI). This measures disease activity and damage in various body sites. The authors are from Rzeszow University and Medical University of Lublin in Poland.
LiPADI subparts:
(1) skin activity
(2) activity at other site (mucous membranes and hair)
(3) damage at all sites
Accessible mucous membranes:
(1) oral cavity
(2) anogenital area
Hair regions:
(1) scalp
(2) other sites with hair
Parameter
Finding
Points
mucous membrane lesion
none
0
linear whitening or white papules
1
1 to 3 erosions or ulcerations
3
4 or more erosions or ulcerations
6
one or more lesions greater than 5 cm in diameter
6
recent hair loss (last month)
no
0
yes
1
non-scarring alopecia
none
0
diffuse thinning, non-inflammatory
1
focal or patchy in 1 quadrant
2
focal or patchy in 2 or more quadrants
3
subscore for mucous membranes =
= (points for oral cavity) + (points for anogenital area)
subscore for hair =
= (points for recent hair loss) + (points for alopecia)
Interpretation:
• minimum subscore for mucous membranes: 0
• maximum subscore for mucous membranes: 12
• minimum subscore for hair: 0
• maximum subscore for hair: 8 (assuming 2 hair regions)
